GSM Pulse discharge

So-called GSM pulse discharge mode in cellular phones requires excellent drain a ability to batteries even at low temperatures. The GSM pulse discharge mode (2 A for 6 ms / 0.15 A for 4 ms) was phed to cells at various temperatures and capacity retention was determined. The result is given in Figure 14 and the cell performance is satisfactory again. The capacity retention is over 40% at-20 °C.
